1990 Map of Indian Spring Mountain

USGS Topo · Published 1990

About this map

The Whitehorse Mountains dominate the eastern landscape of this 1990 survey, where the rugged terrain meets the level expanse of Julia Glover Flat. This Siskiyou County territory is defined by the overlap of the Shasta National Forest and Modoc National Forest, revealing a remote volcanic and timber-rich environment. Geologic and natural landmarks are prominent, including the Mayfield Ice Cave and several water sources like Mayfield Spring and Indian Spring. Evidence of early 20th-century transportation and industry persists in the form of a Railroad Grade cutting through the forest and a Cinder Pit near Hambone Island, reflecting the area's history of resource extraction and infrastructure development on the high plateau.
